PATRICK CUNNINGHAM, OF NEW BEDFORD, MASSACHUSETTS, ASSIGNOR TO THE APPLEGATE BOOT AND SHOE LASTING COMPANY, OF PORTLAND,

MAINE.

LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 424,861, dated April 1, 1890. Application filed July 1, 1889. Serial No. 316,236. (No model.)

To aZZ whom it may concern:

Be itknown that I, of New Bedford, cou Massachusetts, have ment in Lasting-Machines, of which the following description,

accompanying drawi in connection with the ngs, is a specification,

like letters and figures on the drawings representing like parts.

This invention hasfor its object 'to improve that class of lasting-machines wherein the edges of the uppe the last by a cord tacks.

r are drawn over upon or cords to avoid the use of The invention herein contained is an improvement on that described in United States Patent No. 393,760..

Herein the cords are shown as acted. upon. by cord-drawing devices shown as clamps at the ends of horizontal rods free to be slid longitudinally in bearings of an oscillating post, the sliding bars having combined ism whereby they may nally when the upper 1s instep of the shoe. I actuating devices for adapted to move. the both directions, engagement with the with them mechanbe moved longitudibeing lasted at the have herein shown the moving the said rods as said rods positively in so that the said'rods when in cords at the instep may be either pushed in the direction to cross the last or be moved laterally away from the last.

\Vhen the clamps on the rods act to pull the cord to draw the edges of the upper along the toe and ball of the last over upon the inner sole, and when the said clamps and rods act to draw the edges of the upperover upon the inner sole at and abo last the said rods are ut the heel part of the or may be swung in the direction of the length of thelast by gearing in engagement with the said posts, the strain at such time on exerted by der the control, preferably,

operator.

To last the toe nior than can be done by the cords being drawn being a treadlo or equivalent lever unof the foot of the e smoothly and rapidly the cord alone,l have provided the machine with a toejaw, which is advanced and mad I per outside the toe of the slack in the d rawe to act against the upthe last just as or after cord has been taken up tipped more or less from a vertical position,

by the movement of the rods referred to toward the heel of the last. The toe-jaws are free to slide in a j aw-holder mounted 011 a pivot arranged parallel to the length of the last, so that the said toe-jaws are free to tip to accommodate for anyinequalities of thickness in stock, as well as to the style of the last. The jaw-holderis also pivoted to turn on suitable pivots or bearings arranged substantially at right angles to the length of the last, and the said holder at its rear end has combined withit an adjusting device,whereby the inclination of the said holder with relation to the bottom of the last may be changed at will, according to the pressure desired and the curvature of the last. The upper to be lasted is placed on a last, and the latter is mounted upon a vertically-adjustable heelpin having means whereby it may also be according to the shapeof the last, and the fore part of the last is permitted to rest upon a toe-rest, which is also vertically adjustable as to height, and which also has combined with it means whereby the toe-rest may be quickly raised and lowered to enable a last to be quickly put into and taken from the machine. The heel-pin is made horizontally adjustable toward and from the toe-rest. The toe-jaws are moved forward and backward in the holder by means of a sector-lever controlled by a treadle actuated by the foot of the operator.

The particular features in which my invention consists will be hereinafter more fully described, and designated. in the claims at the end of the specification.

Figure l is a top or plan View of a lasting- Inachine embodying my invention; Fig. 2, a partial front elevation of the same; Fig. 3, a vertical section in the line x :0, Fig. 2. Fig. 4 shows the rocker-pivot B Fig. 5, a sectional detail of the cord-drawing rods and part of their actuating devices. Fig. 0' is a detail showing the under side of the little dog, which 5 aids in holding the draw-cord; Fig. 7, a detail showing the cam-plate at the under side of the jaw-holder; Fig. 8, a detail showing the under side of the toe-j aws mounted on the toej aw carriers. Fig. 9 shows the shoe enlarged,

with the draw-cord laid in the pockets composed of loops of needle-thread, the d raw-cord being represented as having been pulled at and about the toe of the last; Fig. 10, a side elevation of the shoe shown in Fig. 9; Figs. 11 and 12, details to be referred to.

The framework of the machine consists of a table A, suitable side legs A, and cross-girts A The bed has erected upon it a stand B, having an overhanging arm B, the forward end of which receives a pivot-stud B parallel to the length of the last, 011 which is pivotcd a rocker-pivot ll, (shown separately in Fig. 4,) it receiving at its ends like pivot-serews 'l", which pass through ears D of the jaw-holder B, the said screws 13' forming pivots at right angles to the length of the last, the pivot B permitting the said holder to tip and enable the jaws (to be described) to adapt themselves to varying thicknesses of stock and shapes of last bottom, while the pivots l3" permit the holder B to be adjusted more or less by or through the screw-threaded link B and the nut 13 to adapt the said jaws to the inclination of the last and the pressure required on the upper at the toe of the last. The link B and nut constitute an adjusting device for the holder 3. The link B is extended through a spring B", of rubber or other material, to enable the jaws to give slightly and obviate tearing the leather.

The under side of the holder has attached to it by suitable screws '6 a cam-plate (J, having two cam-slots O to receive the roller or other usual studs of the jaw-carrying lever C, mounted to turn on a stud C", extended downwardly from one end of a sliding rack bar 0 the said carriers and rack-bar being located in the space between the said holder and its cam-plate, as best shown in Fig. 3.

The jaw-carriers have attached to them by suitable screws 2 2 the two jaws a, b. The edges of these jaws which contact with the upper at the toe of the last are curved and are fitted together, so that the junction of their edges is substantially central with the pivot 0 on which the toe-jaw carriers turn as they are being moved forward by the sectorlever D, (to be described,) the said jaw-carriers being at the same time moved to partially close the jaws by the studs (3 travelingin the cam-slots 1. By this construction the edges of the toe-jaws, which contact with the upper on the last at the center of the toe of the last,

are located farther back than usual, so that after the edges of the toe-jaws have come in contact with the edge of the upper, the jaws being then open, the said edges, as the jaws are thereafter moved forward and closed simultaneously to wipe the edges over the inner sole, have given to them much less movement than were the acting edges of the jaws located ahead of the said pivot, as in jaws such as heretofore used, this less closing movement of the ends of the jaws in contact with the toe of the upper obviating bunching or crimping the upper immediately at the end of the toe of the last.

The end of the toe-jaw a has a curved tongue 3, which enters a slot 4; in the jaw I), so that as the said jaws are closed there is not left a gap between them into which may enter the upper of the shoe being acted upon to thus form a crimp or leave a mark.

The operating mechanism for the sector-lever D is herein shown as alink D, jointed to it and to a lever D pivoted at D", and a second link D, jointed by pin 5 to the inner end of a treadle D (see Figs. 1 and 2,) the de pression of the said treadle by the foot of the operator causing the said rack-bar C to be moved forward, a weight, as D, on the rear end of the said lever moving the treadle into the position shown in Fig. 1, whenever the operator removes his foot from the treadle, thus retracting'the said slide-bar and jaws.

The toe-rest is composed of a suitable eoneavcd pad E, attached to the upper end of a screw-rod E, provided with an adjusting-nut '7 and a set-nut 8, the said nut 7 resting upon the top of a eam-block E having cams or inclines at its under side and resting loosely on a hub E, having cams or inclines at its top. The cam-block has a handle 70, by which it may be turned quickly when it is desired to raise or lower the toe-rest to clam p a shoe and last, or to release the same,the adjustment of the nuts 7 8 placing the toe-restat the proper height to receive the last when the cam-block E is turned to let the toe-rest down. The lower end of the toe-rest rod E is grooved, as at 12, to receive a projection or screw 13, the latter preventing the rotation of the said rod, yet permitting the said rod to be easily lifted from the cam-block. The cam-hub is ad.- justably secured to the table bya bolt 14 entering a nut 15.

The heel-pin F is shown asa screw-threaded rod entering a nut F, having a handle 18, and resting upon a tipping plate F provided at one side of the said rod with an adjusting device 16, (shown asascrew,) the said tipping plate having its fulcrum at 17 upon a sliding carriage E resting on the table A. The heelpin F is extended loosely through the said carriage, and below the table is provided with a nut 19, having ears 20 at each side, (see Fig. 2, where the front of the table is broken. out, which ears, as the nut F is turned partially around on the quick threads of the heel-pin, raises the heel-pin and brings the said ears 20 against the under side of the table, thus locking the carriage and heel-pin in place at the proper distance from the toe rest, according to the length .of the last. Movement of the adjusting device will change the inclination of the plate F and thus tip the heel-pin more or less, as required, to enable the heel-pin to correctly hold the lasts notwithstanding variations in the holes in the lasts for the reception of the heel-pin.

The table A has like tubular bosses G, which receive the shanks of tubular posts G,

IIO

provided at their lower ends below the said table with gears G which are engaged by bevel-gears G fast on a rock-shaft G held loosely in suitable bearings in hangers 22, depending from the table, the said rock-shaft having an arm G to which is connected a hub G, attached to a treadle G mounted to turn on a rod G the opposite end of the said treadle having an'adjustableweight G The top of each tubular post G, which, as described, may be partially rotated when desired, has a forked head 23, in which by a suitable pivot-pin 24 is pivoted a sleeve d having, as shown, two rolls (1' cl, over which is extendeda suitable cord, strap, or belt 61 one end of the said cord, as herein shown,

being attached to a cord-drawing rod f by a screw 25, the opposite end of the said cord being attached (see Fig. 5) to a nut 26, made adjustable on the said rod'by an adj ust-ing screw 27. The said cords between their endspass each over a like pulley f, and like guidepulleys f f herein shown as turning on the said hangers 22. As the pulleys f are rotated partially, they actuate the said cords and cause the longitudinal movement of the said rods f. These pulleys turn on like pivots f and each pulley, as herein shown, has suitable lugs to receive and hold a rod f, on which is a block f, having a pin, which is engaged by a rod f each rod f being jointed to the rear ends of like treadles f mounted loosely on the rod G and weighted at f The outer ends of these two treadles are (see Fig, 1)

placed sufficiently close together to enable the operator to depress both of them by one foot and at a simultaneous operation, if desired.

Each treadle G and f has co-operating with it a like ratchet or holding lever g, pivoted at g and acted upon byaspring-pressed plunger 9 (see Fig. 3,) which normally acts to keep the ratchet toothed ends of the said holding-levers pressed outwardly, as in Fig. 3, ready to engage projections of and hold the outer ends of the said treadles down in the position in which they are left by the foot of the operator; but the operator by engaging the upper ends of the said levers may readily move them to free the treadles and let the weights attached'to their opposite ends act to elevate the front endsof the treadles.

e cause'of the breakage of a draw-cord, it should be desired to move the draw-cord rods in the opposite direction or -so' as to start and traverse across the last rather than to move away from it, then the operator by engaging the levers g pivoted at F, will, through the link 9 connected to the blocks f cause the said blocks to be slid on the rods f to the opposite side of the centers f 4 of the pulleys f and thereafter by the depression of the treadles f the pulleys f will be moved partially in the direction opposite the arrows thereon. The front end of each draw-cord rod will preferably contain a notch, as 28, (see Fig. 5,) to enable it to hold upon a draw-cord, and so, also, the said draw-cord rods near their ends will be provided with one or more projections, as 29 30, and to aid in better holding the drawcord with small dogs 31, pivoted at 32, as shown best in Fig. 5, each of the said dogs beingprovided at its under side with a spring, as 33, so connected with the said dog and with the said rod as to normally turn the dog inthe direction of the arrow 34. (See Fig. 1.)

From the foregoing description it will be understood that the draw-cord rods may be swung backward and forward about a vertical pivot, that they may also be turned up and (shown as composed of parts of loops It of thread inserted by a sewing-machine,) the 'said draw-cord, as herein represented, beingsupposed to be laid upon the upper under the descending needle, so that the needle-' threadcrosses the draw-cord at intervals of two, three, or more stitches. In introducing this draw-cord into the pockets of loopsI prefer to start at the heel-seam with the outside of the upper uppermost on the bed-plate of the sewing-machine and insert the said stitches, laying the draw-cord under them by a suit able finger, much after the manner of an embroidery device, until the stitching arrives near the toe or the toe-cap, as at 43, when the stitching will be stopped and the upper will be turned over, so that the inner side of the upper will be uppermost, and then the stitching will be commenced at the opposite side of the upper, as at 40, and will continue about the toe in the direction of the arrow 41 until the stitching was left off to enable the drawcord to be carried to the opposite side of the upper. On arriving at the point 43 again the machine will be again stopped, the upper,

turned over, so that its outer side'is again uppermost, and then the stitching will be commenced on the opposite side of the upper,

or at the point 44, and will continue along 'the upper to the end of the heel, where theslack was left in the draw-cords extending across the ball of the inner sole and last to enable each half of the draw-cord to be caught IIO . I I 5 the stitching arrives at the point 43, where by the projections 29 30 and the dog 31, as shown in the said Fig. 1. In this condition of affairs the operator will examine the upper and lining at the toe of the last to see if they are in proper condition, and if not with his fingers or otherwise he will smooth them, and thereafter he will put his foot upon the treadle G and depress it far enough to swing the draw-cord rods horizontally back toward the heel of the shoe for a distance sufficient to take up all the slack in the draw-cord eX- tending from the said rods about the toe of the upper, which slack having been taken up the holding-lever g, co-operatin g with the said treadle G is made to catch and detain it in its depressed position. The operator then examines the toe of the upper and sees if it has been properly gathered, and thereafter the operator with his .foot upon the treadle (1 causes the toe-jaws to be moved forward until their edges meet the upper at the toe of the last, the forward movement of the toejaws being continued, the jaws at the same time being slowly closed until the toe-jaws by an inward motion have wiped the upper smoothly over upon the toe of the inner sole, and thereafter the holding-lever g, which acted to hold the treadle G is released, permitting the weight G"- to turn the drawcord rods back into their original position, when the operator will detach or loosen them from the projections and dogs referred to. \Vhile the toe-jaws yet hold the upper upon the last the operator takes hold of the drawcords, which were knotted together at the heel of the upper, and by a strong pull exerted by his hands takes up the slack in the draw-cord previously made by the described movement of the draw-cord rods, and again ties or fast ens the ends of the draw-cord at the heel. This done, the operator will again bring the rods in position to engage the draw-cord, but this time at or near the instep of the upper at both sides thereof, and if the cord is to be pulled it will be made to engage with the projections 20 30, the draw-cord red at one side of the last or upper engaging the drawcord at'the opposite side of the last or upper which done the operator by depressing both treadles f, as described, will, through the mechanism set in motion by them, move the two draw-cord rods in the direction of the arrows thereon in Figs. 2 and 5, and pulling the said draw-cords, as represented in the detail Fig. 2, or until all slack in the draw-cord has been taken up. This pulling of the draweord is in the proper direction to not only cause the edges of the upper to be pulled over the edge of the inner sole, but also to cause the upper to be fitted snuglyto the last. This done, the loops of the draw-cord shown in Fig. 12, as last made, will be disengaged from the draw-cord rods, and will be cut and tied together from side to side, as represented in the detail Fig. 11. This completes the lasting of the upper, and the toe-jaws will be released and the cam-block E turned to lower the toe-rest, and the nut F be turned to release the heel-pin, leaving the last in condition to be readily removed. In case of the breakage of the draw-cord, so that there is not sufficient amount thereof to be pulled in the direction stated at the instep, then the operator may, while the said cord is properly tied together, place the end notch 28 of a drawcord rod against the draw cord, each rod against the draw-cord 'at that side of the shoe next to it,'and will move the levers g to carry the blocks f to the opposite ends of the rods f and thereafter by the depression of the treadles f the rods f will be pushed in a direction opposite the arrows thereon in Figs. 2 and 5, and will take up the slack in the draw-cord and fit the upper to the instep of the last.

The particular method herein described of inserting the draw-cord and carrying it from one to the other end of the edge has been made the subjectrmatter of another application, Serial No. 316,743, to which reference may be had.

By the employment of the draw-cord rods, as described, the operator may engage the said rods in his han d as they are being moved by the treadle, and may assist in their movement or may retard their movement as the exigencies of the upper or of the cord demand, the fact of having the draw-cord rods in his hands enabling him to better last the toe and other parts of the upper than can be done with the devices which act upon the drawcords flexibly, as in the patent referred to.

I have herein described and illustrated the draw-cord as applied in a certain way; but I do not desire to limit my invention to the exact construction of the pockets of thread-loops in which I have introduced the said draweord,nor to the particular direction taken by the draw-cord in its passage about the upper from heel to too, as I may insert the draw-cord in any other usual or well-known manner and yet my improved devices for pulling the said draw-cord be operated to great advantage.
